Occupant safety
Safety guidelines for the seat belt,
emergency tensioning device and
air bag
Warning!G

Damaged seat belts or seat belt that
were highly stressed in an accident
must be replaced and their anchoring
points must also be checked. Only use
seat belts installed or supplied by an au-
thorized Mercedes-Benz Center.

Air bags and pyrotechnic emergency
tensioning devices (ETDs) are designed
to function on a one-time-only basis. An
air bag or ETD that is deployed must be
replaced. PRE-SAFE
® has electrically
operated reversible pre-tensioners in
addition to the pyrotechnic ETDs.

Do not pass seat belt over sharp edges.
They could tear.

Do not make any modification that could
change the effectiveness of the seat
belts.

Do not bleach or dye seat belts as this
may severely weaken them. In a crash
they may not be able to provide ade-
quate protection.

No modifications of any kind may be
made to any components or wiring of
the SRS. This includes changing or re-
moving any component or part of the
SRS, the installation of additional trim
material, badges, etc. over the steering
wheel hub, front passenger front air bag
cover, outboard sides of the seat back-
rests, door trim panels, or door frame
trims, and installation of additional
electrical/electronic equipment on or
near SRS components and wiring. Keep
area between air bags and occupants
free from objects (e.g. packages, purs-
es, umbrellas, etc.).

Do not hang items such as coat hangers
from the coat hooks or handles over the
door. These items may turn into projec-
tiles and cause head and other injuries
when the window curtain air bag is
deployed.

Air bag system components will be hot
after an air bag has inflated. Do not
touch.

Never place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.

In addition, improper repair work on the
SRS creates a risk of rendering the SRS
inoperative or causing unintended air
bag deployment. Work on the SRS must
therefore only be performed by qualified
technicians. Contact an authorized
Mercedes-Benz Center.

For your protection and the protection
of others, when scrapping the air bag
unit or emergency tensioning device,
our safety instructions must be fol-
lowed. These instructions are available
from any authorized Mercedes-Benz
Center.

71 Safety and Security
Driving safety systems
EBP
The Electronic Brake Proportioning (EBP)
enhances braking effectiveness by allow-
ing the rear brakes to supply a greater pro-
portion of the braking effort in straight line
braking without a loss of vehicle stability.ESP®
The Electronic Stability Program (ESP®) is
operational as soon as the engine is run-
ning and monitors the vehicle’s traction
(force of adhesive friction between the
tires and the road surface) and handling.
The ESP
® recognizes when a wheel is spin-
ning or if the vehicle starts to skid. By ap-
plying brakes to the appropriate wheel and
by limiting the engine output, the ESP
®
works to stabilize the vehicle. The ESP® is
especially useful while driving off and on
wet or slippery road surfaces. The ESP
®
also stabilizes the vehicle during braking
and steering maneuvers.
The ESP
® warning lamp v in the instru-
ment cluster flashes when the ESP® is en-
gaged.
The ESP
® warning lamp v in the instru-
ment cluster comes on when you switch on
the ignition (
page 344). It goes out when
the engine is running.
Warning!G
When the EBP is malfunctioning, the ABS,
BAS, BAS Plus* and ESP® are also switched
off.
If the EBP is malfunctioning, the brake sys-
tem will still function with full brake boost.
However, the rear wheels could lock up dur-
ing emergency braking situations, for exam-
ple. You could lose control of the vehicle and
cause an accident. Adapt your driving style
to the changed driving characteristics.
Warning!G
Never switch off the ESP® when you see the
ESP® warning lamp v flashing in the in-
strument cluster. In this case proceed as fol-
lows:

While driving off, apply as little throttle
as possible.

While driving, ease up on the accelera-
tor.

Adapt your speed and driving style to
the prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid.
The ESP
® cannot prevent accidents result-
ing from excessive speed.

264 Control systems
Instrument cluster control system
The control system is activated as soon as
the SmartKey in the starter switch is
turned to position2 or as soon as the
KEYLESS-GO* start/stop button
(
page 346) is in position2. The control
system enables you to:

call up information about your vehicle

change vehicle settings
For example, you can use the control sys-
tem to find out when your vehicle is next
due for service, to call up statistical data
on your vehicle, and much more.
The control system relays information to
the multifunction display.
Multifunction display
1Line for main menus
2Text field in multifunction display
Settings, functions, submenus as well as
any malfunctions are shown to you in the
text field.
Warning!G
A driver’s attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others, se-
lecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions per-
mit it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximate-
ly 14 m) every second.

285 Control systems
Voice Control* introduction
Voice Control* introduction
The Voice Control System gives you the ca-
pability to control the following systems on
your vehicle using spoken commands:

Telephone* (page 289)

Navigation (page 296)

Address book (page 306)

Audio (page 309) (AM/FM radio,
CD/DVD changer, MP3 player)You control these systems using spoken
commands. Moreover, controls such as
the buttons on the multifunction steering
wheel (
page 287) allow you to keep your
hands on the steering wheel.
The command vocabulary consists of
approximately 300 ready to use phrases.
The Voice Control System recognizes com-
mands and number sequences, irrespec-
tive of the speaker. To optimize speech
recognition for your voice follow the indi-
vidualization process (
page 330).
You can use the Voice Control System to
call up all of COMAND’s main menu items,
with the exception of the main menus for
“Vehicle” and “Navi”.The commands and digit sequences can be
spoken without pausing between the indi-
vidual words. If an unavailable or incorrect
command is used, the Voice Control Sys-
tem will prompt you for a new command by
asking “Please repeat” or “Please repeat
your entry”.
In order to provide for a safe and comfort-
able dialog, the Voice Control System ac-
knowledges important commands.
